<p>所以只能通过编译源码的方式安装zsh。</p>
<ol>
<li>
<p>下载最新版源代码。最新版源代码可以在 <code>https://zsh.sourceforge.io/Arc/source.html</code>中获取。</p>
</li>
<li>
<p>安装编译依赖</p>
<pre class="line-numbers language-bash" data-language="bash"><code class="language-bash">yum <span class="token parameter variable">-y</span> <span class="token function">install</span> gcc perl-ExtUtils-MakeMaker ncurses-devel<span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>

<p>注意将zsh添加到shells中时，要填写正确的zsh路径，因为我在执行./configure的时候没有指定安装的位置，所以默认是/usr/local/bin/zsh，不确定的话，执行 <strong>whereis zsh</strong> 命令查看具体的路径。</p>
</li>
<li>
<p>将当前的shell改成zsh：<code>chsh -s /usr/local/bin/zsh </code></p>
</li>
</ol>
<p>此时，zsh最新版就安装完成了。</p>
<p>安装 <code>oh-my-zsh</code>：<code>sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"</code></p>
<p>安装powerlvel10k：<code>git clone --depth=1 https://gitee.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k</code></p>
